A force #vecF = (3xy -5z)hatj + 4zhatk# is applied on a particle. The work done by the force when the particle moves from point #(0,0,0)# to point #(2,4,0)# along the path #y = x^2# is?

Explanation:
Use the definition of work,
Instead using unit vector notations, let's use coordinate to represent the vectors, i.e.,
The above is the work done alone the path
At point (2,4, 0),
The units are not specified, hence the work done has not unit, otherwise it is assumed as
